Title: Spray gun having a fanning air turbine mechanism
Inventor: THIEL LEONARD V
IPC: B05B7/12
Filed: 1989-11-30
Granted: 1994-03-15
Abstract: SPRAY GUN HAVING A FANNING AIR TURBINE MECHANISM              ABSTRACT      A spray gun including a turbine mechanism for reducing the turbulence of fanning air to more effectively control the shaping of a conical spray pattern.  A spiral flow of fanning air is created by  the  turbine  mechanism.     The  amount  of pressurized  air  flowing  through  the  turbine mechanism is controlled by a valve mechanism to provide a greater or lesser amount of fanning air. The improved spray gun is particularly useful in paint spray systems wherein air having a flow rate in excess of 5 CFM and a delivery pressure of less than 15 psi over atmospheric is communicated to the spray head of the spray gun.  In one embodiment, the turbine and valve mechanisms include first and second sets of circumferentially-spaced inclined vanes, respectively, which cooperate to create the spiral flow of air.  The valve mechanism includes an annular valve member which supports the second set of vanes.   The turbine mechanism includes a turbine member which supports the first set of vanes.   The valve member is mounted for rotary movement on the turbine member to move between open and closed positions to thereby control the amount of pressurized air flowing through the turbine mechanism.   The valve member is maintained in a predetermined, axially spaced position from the turbine member by a locking ring to prevent air leakage therebetween.

Title: Helical bend proof testing of optical fibers
Inventor: CHESLER RONALD B
IPC: G01N3/00
Filed: 1990-03-07
Granted: 1994-07-12
Abstract: HELICAL BEND PROOF TESTING OF OPTICAL FIBERS               ABSTRACT OF THE DISCLOSURE        An  optical  fiber  is proof tested by bending it  relative  to  the  fiber  axis  by  a preselected amount,  in all directions and at all locations along the  length  of  the  fiber.    In  one approach, the optical  fiber   is  wrapped  around  a  cylindrical mandrel  in  a  helical  pattern  and  drawn over the mandrel   through   its  entire  length.    With  the preferred  helical  angle  of  about  45 degrees, two wraps  of the optical fiber around the mandrel ensure that   all   of   the  fiber  will  be  bent  in  all directions.    If  a flaw exists in the optical fiber that  would  cause  failure  at any amount of bending below  that  of  the  preselected  amount, this proof test  will  cause  the fiber to fail so that the weak point may be eliminated.

Patent CA-2048755-C (CA)
Inventor: HUBE RANDALL R
IPC: G06F17/21
Filed: 1991-08-08
Granted: 1995-09-26
Abstract: In a printer system which allows printing in multiple fonts, where the font to be used is specified in an encoded document to be printed, an operator designation of font equivalency is provided which specifies acceptable font substitutes of available fonts for unavailable fonts. Upon detection of a document specification of an unavailable font, a print controller searches a mapping of known fonts to available fonts to determine if an equivalent font has been designated. The mapping is operator-set in accordance with the operator perception of equivalence. Font equivalency mapping may be a yes/no equivalent, indicating substitution or job fault, or the mapping may have a multilevel substitution hierarchy, in which degrees of equivalency are determined by the operator, and result in different warnings or machine operations dependent on different degrees of equivalency. An operator may also program the job to allow printing if the equivalency falls within a certain degree, changing that degree depending upon customer sensitivity to font use.

Title: Floppy disk container
Inventor: UCHIDA HIROMICHI
IPC: G11B33/04
Filed: 1993-03-24
Granted: 1996-12-17
Abstract: A floppy disk container comprises a plate having an adhesive tape or agent applied to a rear face thereof.  Three edges of a flexible plastic film of an approximately square shape are fastened to the plate, and the remaining edge of the film is free from attachment to the plate and positioned at a mid portion of the plate in order to obtain an upwardly opening insertion opening of the floppy disk container.  Thus, a bag-shaped floppy disk container is obtained.  A pair of stoppers are formed to protrude from an upper portion of the front face of the plate at positions just above the top edge of the floppy disk when the floppy disk is in the container, so as to abut the top edge of the floppy disk and prevent the floppy disk from falling out of the container.   In addition, a transverse elongated ridge in parallel with the insertion opening is formed on the front face of the plate between the insertion opening and the stoppers,  in order to leave a gap between the top edge of the floppy disk and the plate.
